Thanks. Been to a meet today and taken a look at a MM still with the side valve in. The bulk head is straight whereas mine is raised in the middle so I presume it has been altered at some point. The first thing to do I know is to assess the engine (it turns by hand) but I am also thinking ahead. App...

I have a 52 MM that has had a OHV engine put in it at some point. The original sidevalve engine and gearbox came with it and I would like to put it back in. No idea why it was swapped.
Does anyone know of any issues I should be aware of??
